Hello, first of all I want to say that I have been using Pd for 6 years on a PC i5 (fourth generation) 16gb ram and Windows 7 ultimate. Pd and other DAWs I have have always worked without any stability problems. A year ago I upgraded to Windows 10 home (I have always optimized Windows following the indications offered by Merging Technologies and some professional DAWS) Today all the software related to audio works perfectly and without any problem except PS that drives me crazy.

Just create a new patch with 2-3 tables and 2-3 signal objects to start the instability in Pd.
The first symptom that appears is the "feeling" of "overloaded". For example, when dragging an object with the mouse, the object is delayed with respect to the mouse pointer (the more the object patch is loaded, the more noticeable the delay is)

If I save the content of a table of only 8820 samples for example (200ms) with [soundfiler], it can take between 2 and 3 seconds to wait until the message appears in the console

It has also happened to me (although on fewer occasions) that when I press a bang button, the button remains pressed in black and Pd blocked (although I am not aware that this problem is directly related to the other comments).

I want to make it clear that I have not had any problems related to the audio, it is with the GUI that makes me think that something is not right. The first of the problems that I have named is the one that I consider serious for me, because it prevents me from working at ease and in the end I end up not going ahead with any patch. This happens to me in version 0.53.0 that I have now and in the previous 4 versions. I have used the same patches on a laptop that I have and everything works normally. I can't get to understand what is really happening and what the blissful problem may be related to, I have asked several Pd users on telegram and they have not been able to help me either...

Any ideas that occur to you will be welcome. Thank you!

@EMR66 Does this happen with DSP off for Pd? Probably not.... so..
What soundcard driver/s are/is Pd using.... this is the most likely problem and "easily/not so easily" fixed using Asio4all.
Could there be a "permissions" problem? Probably not as audio is working correctly.
I stayed with win7 ultimate..... and probably always will for my audio laptop..... as it works... but that means that I cannot help you much.
Asio4All should fix the problem, but setting it up correctly can take a little time unless you are very familiar with audio driver setup ...... https://forum.pdpatchrepo.info/topic/11324/gui-horribly-slow

The problem keeps happening even with the dsp turned off. I have created an empty patch with about 50 "bang" buttons to test, I have dragged one of them with the mouse and it is a horror to see Pd in this way... I would not dare to say that it is unusable, but it is close. ..

I will continue to investigate the ASIO driver issue further as you have suggested.

Thanks for your help.

In the interest of "differential testing," you might try PlugData -- https://github.com/plugdata-team/plugdata/releases -- esp. the Standalone.

This replaces Pd's GUI.

If PlugData shows the same problem, then the problem is in the interpreter or audio layers.

If PlugData does not show the same problem, then the issue is in the GUI.

@EMR66 I remember that audio driver problems can cause this GUI lag even with Pd DSP off.

@EMR66 If memory serves I saw a bug report about slow gui introduced in 0.52, don't recall the details but you could check the github. I also have such issues on linux but they are not so bad, fairly certain I just decided to accept them because I saw the bug report and figured that it would eventually be dealt with but perhaps not. Have yet to get around to upgrading to 0.53 either. For me it is just a slight sluggishness in response of the GUI in even small patches but I tend to make very large patches of the sort which have always caused issues with pd so this slight sluggishness was never much of an issue for me.

@oid I don't know. I have had no lag with gui's in any version of Pd since I sorted ASIO and LAN network issues in Win7..... even in massive patches with 64 vsliders live on screen constantly updating from 40+ OSC network connections with constant high data flows.... and my intervention through the GUI.
As long as audio is running smoothly without buffer issues Pd control rate processing has ample time to do a massive amount of processing between audio ticks.
Even on an I5 1.7GHz which is not as fast as the machines that some are having problems with.
Pretty sure it can be resolved in any OS.
David.

So, if I understand correctly, and taking into account that I have been using Pd with the same equipment and the same interface, and the only thing that has changed is that I am now using Windows 10, I must think that where the conflict is in "Pd and windows 10"??

If so, I have a big problem because for other reasons I will not return to Windows 7 (although I really want to)

Another thing I want to comment on is that the BIOS is possibly misconfigured because the battery is running out (when turning on the PC the message "the Bios has been reset" appears and the clock time is also slipping)

Due to my ignorance, I don't know if this could be related to the problem, although as I already said, all the software I use doesn't have any problem...

I will continue to investigate even if I have less and less hope...

Thanks to all for the help!!

@EMR66 Not necessarily the cmos.
I have just one old laptop (a very old laptop) that loses its bios settings.......... BUT only if left unplugged until the main battery runs completely flat. So its cmos backup battery is dead, but that is only a problem when the main battery is empty. It is a "backup" cmos battery after all.
It could be memory problems.... RAM... that report incompatibility with a previous saved state on shutdown or fastboot .... or some other problem.
But change the cmos battery first..... a simple and cheaper solution if it works....!
Also I believe widows10 hibernates rather than shutting down. Is your main battery good, and have you ever completely shut the computer down since the upgrade?
